BR7ES gaped at .022

 

I was gonna say gap them to .018 and give it a go.

 

In 1st pic gap looks way big to me. Have you verified the plug gap? An 8 is a relatively cold plug, FYI.

What NGK "8" plug is this exactly? Is the plug pictured an NGK BPR 8ES?

 

BPR9ES is way too cold for street use even on Meth IMO.

 

Gap them to .019 and if u are still on the stock ignition running E85 you need to look into upgrading to a COP Igniton System...The stock ignition becomes weak once you start adding good power adders in to the mix especially if u are running E85...i had the same problem...gapped my NGK Iridium IX's to .019 and the misfire stopped...once u start having to close the gap that small its telling you that your ignition system isn't providing enough amperage to provide a spark that can jump the gap under that amount of load and fuel consumption

 

how long were those plugs in the car? There should be carbon up two or three threads. Are you spraying anything?
I don't read plugs well, but the slightly yellow ground strap tip is or could be from additives in the gas. The fact that there is NO carbon on the threads worries me, maybe thats a deal with E85(?) If its not typical of e85 then I'd add more gas just to see if there is something fishy with your afr.
btw, if you are interested in plug reading , though its more for one offs and carbed cars read here

Im on 93 now. Those plugs have maybe 200 total miles on them. There BPR8EIX gapped to .023.

 

Yeah, it is running way too lean. There should be an ash color. It is running too lean.

 

do you have cop? i would suggest borrowing a spoolin up from someone and see if that helps.

 

You're not going to see carbon on any threads with those plugs, that part of the plug is not protruding into the combustion chamber. As far as signs of a lean condition I don't see it. Can you get a few picture of the plugs in focus instead of your fingers in focus? You really don't want to spend the $10 to get the plugs that are used by "all the fast guys"? http://www.dansmc.com/spark_plugs/sp...s_catalog.html

 

part store had to order BPR7es plugs, Ill try them tomarro. im going to try .018 with both the 8eix and 9es in a little bit.

 

forget the "P" get the cheap copper plug (BR7ES) you can them at a good motorcycle shop or auto parts store or find them on ebay for about $1.25 each

 

well is she runnin yet?
